We propose a model combining the first-order liquid-liquid and the
second-order ferroelectric phase transitions phenomenology to explain
various features of the $\lambda$-point of liquid water. We suggest
that the long-range dipole-dipole interaction of water molecules leads
to a ferroelectric phase transition, which occurs only in the low-density
component of the liquid and is the origin of the singularity of the
dielectric constant recently observed in experiments with supercooled
liquid water in nano-porous materials. Finally, we establish the model
parameters and prove the consistency of the combined model by comparing
its predictions with experimental data and the results of recent MD
simulations.
